It looks pretty cool so far. Forgive me as I don't know the internals of QML as
well as I should, but what about if you could set a std::function lambda as a
custom setter, and if set that code runs? Or something similar?
QProperty<QString> firstname("John" /* to be set with custom setter*/, /*
custom setter*/ [&]{
value=md5sum(value); emit valueChanged(value) }
);
Or set it as a member function later, but that would be messy unless you had a
subclass to always do it.
Feel free to ignore any or all of this, just thinking out-loud.
